I guess this is a better place for this thread since the PC owners have either already made something like this or can easily do so. I own Skyrim for the 360 and have not yet acquired a copy for the PC.

I watched the week with Dice video thing and I noticed something not mentioned. Farming.
My idea was for the player to acquire 1-2 seeds every time he/she consumed certain plant-able ingredients like Nirnroots, Red Mountain Flowers, Nightshade and so on. Also being able to purchase seeds to grow food like tomatoes and cabbage and so forth. If they implement the build a house feature, I imagined there being a field for the user to plant crops. There would be 5-6 rows, and they'd function like a bookshelf. For example, the user could press "A" (Xbox360) on a row and it would read "you can place 12 more seeds in this row". After a certain amount of time (maybe two weeks or something, depends on crop) there would be your harvest.

Good or bad idea?

Good idea. It could be made relatively easily for the PC users by the mod community, but mods aren't gonna happen on consoles. I hope Beth makes stuff like this so you guys can use it on consoles.

It would give a reason for the Garden in Riften's House. As well as the one within the Dark Brotherhood place (If you wish to count it so)

It could come with the idea of players building their own homes?

What is this harvest moon?
Joking i love the idea, it would be nice to own your own farm.

Not a bad idea. I would certainly be on board with that.

Good idea, I like it.
